ABLATION DEVICE WITH MULTIPLE ABLATION MODES |
摘要 |
Devices, systems, and methods for performing ablation therapy on body tissue are disclosed. An example ablation device for treating body tissue includes an ionically conductive balloon and a radio-frequency electrode that delivers RF energy into a distal section of the balloon. The balloon is configured to transmit the RF energy in a direction distally towards a leading end of the ablation device. Multiple ablation electrodes on the device can be used for providing lesions of different size or shape. |

1. A method for performing ablation therapy on the body of a patient, the method comprising:
advancing an ablation device to a target body tissue region, the ablation device including an inflatable balloon coupled to an elongate shaft, a first electrode disposed within an interior space of the balloon, and a second electrode located outside of the balloon; injecting an electrically conductive fluid into the interior section of the balloon and inflating the balloon from a collapsed state to an expanded state within the body; selectively energizing the first electrode and generating a first RF electrical field within the balloon interior; forming at least one ablation lesion within the body tissue using the first RF electrical field; selectively energizing the second electrode and generating a second RF electrical field; and forming at least one ablation lesion within the body tissue using the second RF electrical field. |
